CARBON REMOVER.

Application filed March 30, 1922. Serial No. 548,095.

To a?! whom it may concern:

Be it known that we, THOMAS F. IBBETSON and THOMAS F. MoRnIsoN, citizens of the United States of America, and residents of Chanute,in the county of Neosho and State of Kansas, have invented certain new and useful Improvements in Carbon Removers,

c lation.

A further object of this invention is to produce a carbon removing tool of the character indicated which can be readily applied to or removed from the piston, the said device being adjustable with respect to the piston to permit it to be employed in connection with pistons of different sizes and in conjunction with grooves of different widths.

A still further object of this invention is to produce a tool of the character indicated which will prove eflicient and which will eifect results without the expenditure of undue time.

Vith the foregoing and other ob]ects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, ref-- erence will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a view in elevation of a piston showing a device embodying the invention applied thereto;

Figure 2 illustrates a sectional view through the groove of the piston, showing the tool inplan and partly in section;

Figure 3 illustrates a perspective view of .the scraper head;

partly in section sh wing he body flexed and the scraper head slightly tilted as the parts appear when operating.

In these drawings 5 denotes a piston of conventional form and it has the usual grooves (i forming seats for the piston rings.

The tool embodying the invention in the presentillustration comprises a substantially circular body portion 7 having arms 8 and 9 extending substantially parallel and constituting a handle. One of the arms 8 has a slot 10 to receive a bolt 11 which extends through an aperture 12 of the other arm, and the two arms are clamped together by a nut 13 to hold the body in proper operative relation to a piston when the device is to be used. The purpose of the slot is to permit the body to be applied to pistons of different diameters, within certain bounds, while at the same time affording means for clamping the arms together by the bolt.

The body has apertures 14 in which the shank 15 of a cutter or scraper head 16 extends, the said shank being secured in any one of the apertures, according to the size of the piston to be treated. The shank is threaded and is held in place in the body by a lock washer 17 of conventional type and a nut 18. At or near the junction of the cutter or scraper head and its shank, a shoulder 19 is formed which abuts the body and forms an anchorage which will prevent oscillation of the shank in the body when the tool is being used, but owing to the resiliency of the body, the scraper will oscillate on its cutting edge which acts as a fulcrum when pressure is applied to the arm 8 in the manipulation of the scraper.

The head has other apertures 20 and 21 in which shanks 22 of the guides 23 are fitted and secured by a nut and washer, preferably as described in connection with the securing of the shank 15, but, of course, these fastenings may be modified to suit particular requirements, but preferably the guides 23 bear against the inner surface of the body and each guide has a rib 24 which enters the groove of the piston from which the deposit is being removed, and therefore, by the manipulation of the handle, the tool may be turned with relation to the piston, resultingin the dislodgment of deposits from the groove, as will be apparent.

The cutter or scraper head may be modified in its "configuration, and itmay be so formed as to be p le of act g, when th device is manipulated, in a clockwise or an an anti-clockwise direction.

It will be apparent from an inspection of the drawing that the body can be made of material which is sufliciently resilient or pliable to permit the arms to separate to produce a clearance that will permit the application of the device to the grooves of a piston or to remove it therefrom.

lVe claim:

In a carbon remover, a substantially circular body of pliable material of greater diameter than a piston with relation to which it is to be manipulated, the said circular body having arms adapted to extend outwardly approximately parallel to each other to form a handle, the said body having apertures a plurality of which are in proximity to one of the arms, guiding members having shanks extending through certain of the apertures, and a carbon removing element comprising a head with one of its edges adapted to bear against the inner wall or" a piston ring groove a shank for carrying the head, the said'shank being secured in one of the plurality of apertures near one of the handles and operative to tilt with the yielding of the pliable material constituting the circular body when pressure is applied to the handle in manipulating the remover.
